Monitoring land use/land cover change impacts on soils in data scarce environments: a case of south-central Ethiopia

To monitor land-use/land-cover (LULC) change and assess its impact on the soil property, the availability of benchmark data is indispensable, which is hardly available in the intensively cultivated regions of developing countries. Our study attempts to solve this problem by generating a benchmark soil data through the development of modified spatial analogue (MSA) method in the context of the Upper Dijo River catchment, south-central Ethiopia. The magnitude and patterns of LULC changes were extracted from air photos and satellite imageries, along with the acquisition of soil samples from the reference and target sites through ground survey. Analysis of digital image processing shows significant LULC changes in a period that spanned three decades. The impact of LULC change on soil quality was assessed by comparing the soil physico-chemical properties sampled from the reference and target sites. The result shows a decline in total nitrogen, organic matter, available potassium and pH levels in soils collected from target sites, which conforms to results reported by studies conducted in data-rich environment. With careful validation, MSA could be useful for monitoring soil property changes in data-scarce environment and generate soil-related parameters for agro-ecological models.     

Livestock mortality in pastoralist herds in Ethiopia and implications for drought response

Participatory epidemiology methods were employed retrospectively in three pastoralist regions of Ethiopia to estimate the specific causes of excess livestock mortality during drought. The results showed that starvation/dehydration accounted for between 61.5 and 100 per cent of excess livestock mortality during drought, whereas disease‐related mortality accounted for between 0 and 28.1 per cent of excess mortality. Field observations indicate that, in livestock, disease risks and mortality increase in the immediate post‐drought period, during rain. The design of livelihoods‐based drought response programmes should include protection of core livestock assets, and it should take account of the specific causes of excess livestock mortality during drought and immediately afterwards. This study shows that, when comparing livestock feed supplementation and veterinary support, relatively more aid should be directed at the former if the objective is to protect core livestock during drought. Veterinary support should consider disease‐related mortality in the immediate post‐drought period, and tailor inputs accordingly.     

Long-Term Indigenous Soil Conservation Technology in the Chencha Area,Southern Ethiopia: Origin,Characteristics, and Sustainability

The purpose of this study is to examine the origin, development, and characteristics of terraces (kella), plus their potentials and determinants for sustainable use in the Chencha–Dorze Belle area of southern Ethiopia. Field surveys were conducted to determine the various parameters of the indigenous terraces and in order to collect samples for radiocarbon dating. To identify farmers’ views of the terrace systems, semi-structured interviews and group discussions were also carried out. Terraces were built and used—as radiocarbon dating proves—at least over the last 800 years. The long-term continued usage of the indigenous terraces is the result of social commitments, the structural features of the terraces, and the farmers’ responses to the dynamics of social and cultural circumstances. We dubbed that the terraces are a success story of fruitful environmental management over generations. Thus, a strong need is to preserve and develop this important cultural heritage and example of sustainable land use.     

Selective feeding programmes in Ethiopia and East Sudan–1985/1986

A survey of thirty-four feeding programmes in Ethiopia and East Sudan was undertaken. Wie differences were found between the two countries and also within Ethiopia. Irrelugar general ration distribution was commonplace in Ethiopia, thus placing an extra strain on selective feeding programmes. The principal admission criteria to Selected Feeding Programmes (SFPs) were weight for height categories. The cut-off stages of the emergency. Useful compasirions between programmes were hampered by such differences, as well as by the different methods of reporting data.
The types of food usd in programmes depended on availability and included high energyu drinks, poridges, take-home pre-mixes and sometimes indigenous foods. A large number of foods e.g. cornedbedef, chicken paté, noodles, da4tes etc. Some added interesting variety and added nutritional value to the diet, while others caused more problems than they solved due to their low acceptability, inappropriate packaging, limited accompanying information and complex an costly preparation. The imlementation of food dination policies by donors and consignees regarding appropriate foodstuffs and their recommended use was considered to be the major solution to this problem.     

Cholera in Sudan: An account of an epidemic in a refugee camp in eastern Sudan, May-June 1985

In 1985 cholera has been a serious problem in the horn of Africa, particularly affecting the many famine victims and refugees in that region. In this paper the history of cholera in Africa is briefly summarized, as is the background to the current refugee situation in eastern Sudan. A cholera epidemic involving 1,175 cases in two adjacent refugee camps in eastern Sudan is described. In this epidemic there were thirteen inpatient deaths and thirty-eight known home deaths from cholera. The management of the epidemic is described in detail. Overall an average of 8 1. of intravenous fluid was used per case, a higher figure than was anticipated, probably because of the unexpected degree of vomiting and the shortage of trained nursing staff.
The relationship between cholera and malnutrition is explored and hypochlorhydria is suggested as the main reason for the increased susceptibility to cholera among malnourished populations. It was observed that severely malnourished adults and children appeared to nave less severe diarrhoea with their cholera, presumably because of reduced mucosal surface area and poor enterocyte function. Finally possible means of aborting cholera epidemics are discussed.     

Long-term dynamics in land resource use and the driving forces in the Beressa watershed, highlands of Ethiopia

Land degradation in the Ethiopian highlands is considered to be one of the major problems threatening agricultural development and food security in the country. However, knowledge about the forces driving the long-term dynamics in land resources use is limited. This research integrates biophysical information with socio-economic processes and policy changes to examine the dynamics of land resource use and farmers' livelihoods in the Beressa watershed for over 40 years during the second half of the 20th century. It was found that there have been substantial dynamics in land resource use in the area. The natural vegetation cover has been extensively cleared, although most of the cleared areas have since been replaced with plantations. Grazing land has expanded remarkably at the expense of cropland and bare land. However, the expansion of cropland was minimal over the 43-year period despite a quadrupling of the population density. Yields have not increased to compensate for the reduction in per capita cropland, and the soil quality appears to be not that good. Though the farmers perceived it otherwise, the long-term rainfall pattern has improved. In response to soil degradation, water shortage, socio-economic and policy changes, farmers have tended to gradually change from annual cropping to tree planting and livestock production to cope with the problems of soil degradation, water scarcity and smaller farms. Income diversification through the sale of wood and cattle dung is becoming a major livelihood strategy. Apparently, however, little attention has been paid to investments in soil and water conservation (SWC) and local soil fertility amendments. In particular, increased erosion and related high nutrient losses in sediments, as well as the removal of potentially available soil nutrients through the sale of manure threatens to damage agricultural sustainability in the area.     

Are soil conservation technologies “win‐win?” A case study of Anjeni in the north‐western Ethiopian highlands

This study measures the impact of fanya juu terraces on the net value of crop income in a high‐rainfall area in the Ethiopian highlands using cross‐sectional multiple plot observations. Using propensity score matching methods we find that the net value of crop income for plots with fanya juu terraces is lower than for plots without fanya juu terraces. This finding makes it difficult to avoid concluding that while the technologies might reduce soil erosion and associated off‐site effects, they do so at the expense of poor farmers in the Ethiopian highlands. Therefore, fanya juu terraces cannot be characterized as a “win‐win” measure to reduce soil erosion. New agricultural technologies need to be profitable to the farmer if they are to be adopted and sustained.     

War and Food Security in Eritrea and Ethiopia, 1998–2000

This paper examines the 1998–2000 'border' war between Eritrea and Ethiopia and its continuing legacies from the perspective of food security.¹ Focusing on the food crisis that hit both countries during the same period and was allowed to develop into a famine in southeast Ethiopia, it argues that this was linked with the war in more ways than hitherto recognised. Such connections can be appreciated only by taking a longer-term view of the decline of the rural economy of which this food crisis was part, factoring in the role played by this and other conflicts that have flared up in the region. An analysis of this kind might have helped donors and aid agencies to respond more effectively both to short-term humanitarian needs in the midst of an inter-state war and to the need for longer-term support for food security in a region beset by endemic conflict.     

Educational,psychosocial, and protection outcomes of child‐ and youth‐focused programming with Somali refugees in Dollo Ado,Ethiopia

Child‐ and youth‐friendly spaces have become a common feature of emergency humanitarian provision. This study reports on the outcomes of child and youth learning centres (CYLCs) in Ethiopia's Buramino Camp established for those fleeing conflict in Somalia. Eighty‐five youths completed baseline assessments shortly after arrival and follow‐up assessments three to six months later. Caregivers of 106 younger children completed similar appraisals. 693 children attending the CYLCs completed pre‐ and post‐educational assessments, which indicated major gains—significant at p<0.0001—in both literacy (younger children, t=9.06; youth, t=13.87) and numeracy (younger children, t=13.94; youths, t=17.10). Children's CYLC attendance increased reports of met needs among caregivers (t=2.53, p<0.05) and youths (t=2.57, p<0.05), and, among caregivers but not youths, significantly moderated protection concerns (t=2.39, p<0.05, and t=?1.90, p=0.06, respectively). There was general improvement in psychosocial well‐being over time for all children; CYLC attendance predicted greater reductions in reported difficulties only among younger children (t=2.51, p<0.05).     

Smallholder farmers’ coping and adaptation strategies to climate change and variability in the central highlands of Ethiopia

This study describes the different coping and adaptation strategies used by smallholder farmers to mitigate the adverse impacts of climate change and variability in the central highlands of Ethiopia. A distinction was made between coping and adaptation strategies, respectively, as short-term and longer term measures. The study surveyed 200 farm households in three districts, and three focus group discussions and three key informant interviews were conducted in each district. All the surveyed farmers perceived at least one aspect of change in the local climate. Their perception of an increasing trend of temperature was supported by meteorological records, while their perception of declining annual rainfall was not supported by actual records in two of the three districts, where positive trends in rainfall were observed. Farmers identified changes in rainfall and drought as their major climate change-related risks. In response, farmers used different strategies to mitigate the adverse effects of climate change and variability. The most widely used coping strategy was selling livestock (85% of the respondents), followed by changing consumption pattern (76% of the respondents). Changing crop planting dates was the most preferred adaptation option (89% of the respondents), while irrigation as an adaptation strategy was used only by 10% of the surveyed farmers. Shortage of water for irrigation (83% of the respondents) and shortage of money to buy necessary inputs (77% of the respondents) were the major barriers to effective adaptation frequently cited in the study area. We conclude that adaptation policy should build on existing coping and adaptation strategies and focus on addressing barriers to the adoption of coping and adaptation measures at different scales.
